

1. TA = 25 °C, VDD = 3.3 V, VDDP = 5 V, VDD(INTF) = 3.3 V, fXTAL = 10 MHz, unless otherwise noted.

2. With an internal 10 k

 pull-up resistor to VDD(INTF).

3. For clock frequency division control (CLKDIV), see Table 12 on page 21.

4. CMDVCC is active low.

5. OFF is an NMOS open drain, with an internal 20 k

 pull-up resistor to VDD(INTF). The pull-up is connected only when used

(i.e. when OFF = high), otherwise disconnected.
